SEVJER TRAP AND PEE CLEANING DEVICE.

Application filed. May S, w25. Serial No. 29,091;

To @ZZ whom t may concern:

Be it known that l, ALBERT O. STENWICK,

1 a citizen of the United States, residing at Red ling, in the county of Goodhue and State of Minnesota, have invented certain new and useful Improvements in Sewer 'lrap and Pipe Cleaning Devices, of which the following is a specitication.

My invention relates to a device for clearing out clogged or partly clogged pipes and is particularly useful for'opening up obstructed sewer pipes, drain pipes, sewer traps and the like.

` The object is to provide a simple, inexpensive and very efcient device particularly adaptable for `use in kitchen sinks, bath tubs, home laundries or any other place where Water .under pressure is available near the opening of the drain pipe or other pipe to be cleaned.

l'n the accompanying drawing:

Fig. 1 isa front view of my device in operative position in a kitchen sink, the latter being shown in longitudinal vertical sec tion. f

Fig. 2 is an enlarged top view of the hand lever of my device.

Fig. 3 is an enlarged partly sectional vertical elevation of the intake end of my device and the attached hand lever.

l? ig. 4t is an enlarged elevation of the upright column of my device looking from right to left in Fig.

Referring to the drawing by reference nu merals, 5 designates the horizontal basin of a kitchen sink having a wall plate 6 adjacent to the face of which is suitably fixed one or more water faucets 7. 8 in 1 designates the usual drain aperture in the bottom of the sin; and 9 is a flange fixed concentrically thereof and is an integral part of the drain pipe 9 connected to or integral with the sewer trap 10 commonly located directly under the sink (see Fig. 1).

My device comprises flexible tubular means one end connected to one of the faucets 7 and the other end registering with the sink drain opening and covering same. Further adjustable means are operatively connected adjacent the opposite ends of said tubular element and co-operate therewithV to send a volume of water under pressure through the clogged pipe as will now be described.

11 is a hose of any suitable flexible material in one end of which is held by a hose clamp 12 one end of a metal pipe L 13, the other end ofsaid L being inserted in the small end of a funnel like member lll preferably made of soft rubber. rl`he said small end of member 14 is held securely about pipe 13 by two opposite clamp menibers 15 adjustable toward each other by a tlunnb screw 15d engaging in the horizontal arms 15@ extending one each from the members 15, said arms being otl'set upwardly as 15b thence horizontally as 15, one arm (15C) at each side of a horizontally disposed lever 16 and secured to it as at 17 by rivets or other suitable means.

In the opposite end of hose 11 is inserted another pipe L 18 held in place by a hose clamp 19, while the other end of the l. is inserted in the smallor intake end of anyr suitable Well known plumbers rubber cups which are usually bell shaped as shown and the latter is held in place by clamp members 21 each having a horizontal arm extension21. Said latter arms 21d are in horizontalA spaced relation to each other and their extremities are secured each as at 22 to the lower end of one of a pair of vertical bars 23. 24 is a suitable screw or bolt engaging both arms 2la or adjusting` them to clamp the members 21 vabout the small end of cupk 20 and retain it rigidly on the pipe L 18. The bars 23 form a vertically disposed column and their upper ends may be held in fixed relation by a rivet passed thro-ugh a spacer 26 and said bars comprise preferably `each a light metal fiat bar both with a row of registering holes 37a The lever 16 likewise has a row of holes 28 and is placed between bars 23 so that any of its holes 28 may be aligned with any pair of holes 27 in bars 23 and a pivot pin 29 may be inserted through the three members 16-23 (see Fig 4).

In the operation of my device and assimiing that a sewer trap just below a sink, as 10 and 5 respectively in Fig. 1, is to be cleared of obstruction, the operator first places cup 20 to cover the drain opening S and holding column 23 vertically he next adjusts arm 16 to about horizontal position 1 relative to the out-let 7 of a faucet 7 and inserts pin 29 in the nearest available holes 27-28 most readily aligned. Then the funnel like member la is pressed upwardly about the faucet outlet?a by vdownward pressure on the outer end of lever 16. The latter being pivoted at 29 its short end is pressed upwardly making a Water `tigl'it contaet about the outlet 7? in' member 14 and simultaneously the same downward pressurewon lever 16 causes thecolujmnrto press vthe resilient rubber cup' 20 to press against the bottom of sink 5 about the4 drain openingv 8 leading to trap 10. Holding the lever 16" down with one hand the, operatOrwturnszon the Water full force at the faucet 7 and the Water is of course vconducted directly to the trap 10 under itsfu'l'lfpressure and any, ob-k struction-in the lat-tzer is forced down to largerseiver pipes and carried away. Y

It is obvious that the device is equally useful in bathv tubs; home laundries orl any' other place Where a drain pipe. or sewer, trap opening is located near a source of Water under pressure.
